# GempakGridLinkRequest
|
|
#
|
|
# This code has been developed by the SIB for use in the AWIPS2 system.
|
|
# Performs a BaseRequest for a grid data from GEMPAK, and stores
|
|
# the float data in the uEngineProducts directory for later transfer.
|
|
#
|
|
# Usage:
|
|
# import GempakGridLinkRequest
|
|
# dataRequest = GempakGridLinkRequest.GempakGridLinkRequest("grib")
|
|
# dataRequest.setDataUri("...")
|
|
# return dataRequest.execute()
